What does a trouble code on an OBD mean?
When a car’s sensors decide that something is amiss, they trigger a message known as a “trouble code,” which may manifest as a “check engine” light or another warning on the dashboard. OBD scanners can check these trouble codes to determine exactly what’s wrong, and clear them from the computer’s memory once the problem is fixed.

Where are OBD2 codes stored in a car?
Diagnostic trouble codes (or fault codes) are obd2 codes that are stored by the on-board computer diagnostic system. These are stored in response to a problem found in the car by the system. These OBD2 codes are stored when a sensor in the car reports a reading that is outside the normal/accepted range (Eg: fuel mixturetoo rich).
